at 12 o’clock, a large double-digit counter dis- 
plays the chronograph minutes. Its operation is 
based on an instant-jump mechanism, which is 
activated at the exact moment that the seconds 
hand completes a full turn. The chronograph’s 
total hours indicator is positioned at 9 o’clock.

THE SECOND TIME ZONE

The presence of a GMT function is a fundamental 
attribute of an explorer’s watch.  In keeping 
with a well-established tradition on Jaeger-
LeCoultre calibres, the second time zone, 
which indicates the user’s customary place of 
residence, is indicated by an additional central  
hour hand, which is complemented by a 24-hour  
display at 6 o’clock.

Use

STARTING THE WATCH

Position the crown in its neutral “N” position 
on the dial.  A few clockwise turns of the 
crown will suffice to start the watch.  It will 
then automatically wind up when you wear it. 
Please note that the crown does not lock when  
winding, even when the watch is fully wound.
